ArvinMeritor Reports Third-Quarter Fiscal Year 2006 Results

Raises Full-Year Earnings and Free Cash Flow Guidance

TROY, Mich. (July 31, 2006) — ArvinMeritor, Inc. (NYSE: ARM) today reported financial results for its third fiscal quarter ended June 30, 2006.

Third-Quarter Fiscal Year 2006 Highlights

•	Record sales of $2.5 billion, up 4 percent from the third quarter of fiscal 2005.

•	Net income was $20 million or $0.29 per diluted share, compared to $46 million, or $0.66 per diluted share in the same period last year.

•

On a GAAP basis, income from continuing operations was $25 million or $0.36 per diluted share, compared to $50 million or $0.72 per diluted share in the same period last year; this decline was primarily due to a labor disruption at an ArvinMeritor brake facility in Canada which unfavorably impacted income from continuing operations by $28 million, after-tax.

•	Income from continuing operations, before special items, was $51 million or $0.73 per diluted share, exceeding the previous guidance of $0.60 to $0.70 per diluted share.

•	Free cash flow was $155 million, an improvement of $96 million from the same period last year.
•	Continued reduction of net debt - down $481 million from the same period last year.
•	Completed new $1.15 billion secured credit facilities that extend maturities to 2011 and 2012.
•	Announced the divestitures of two additional businesses within Light Vehicle Aftermarket (LVA).

“Our results for the third quarter of fiscal 2006 build upon the continued execution of our strategic initiatives, including previously announced restructuring activities and our ongoing focus on operational

performance,” said Chairman, CEO and President Chip McClure. “However, we cannot discount the significant impact of the labor disruption that occurred in June at our brake facility in Tilbury, Ontario.

“We regret the disruption and inconvenience this temporary work stoppage had on the production schedules of certain customers, but we are pleased that this situation was quickly resolved. We are back on track and running at full capacity to provide the superior support and service our customers have come to expect from us. Excluding the impact of this disruption, we are proud of the performance we delivered in the quarter, exceeding the top end of our guidance range.”

Third-Quarter Fiscal Year 2006 Results

For the third quarter of fiscal year 2006, ArvinMeritor posted sales of $2.5 billion, a 4-percent increase compared to the same period last year, and a record quarter for the company. The primary factors contributing to the increase were improved Light Vehicle Systems (LVS) sales in Europe and Asia/Pacific, and strong growth in the company’s commercial specialty business, which provides a comprehensive line of components for vehicles including fire and rescue; construction and utility; military; school buses; motor homes and custom chassis.

Operating income was $47 million, down 49 percent, compared to $93 million in the prior year’s third quarter, primarily due to the Tilbury labor disruption.

(more)

Income from continuing operations was $25 million or $0.36 per diluted share, compared to $50 million or $0.72 per diluted share a year ago. Income from continuing operations, before special items, was flat from the same period last year at $51 million or $0.73 per diluted share.

The company recorded a loss from discontinued operations of $5 million or $0.07 per diluted share, compared to a loss of $4 million or $0.06 per diluted share last year.

Fourth-Quarter and Full-Year 2006 Outlook

The company’s fiscal year 2006 outlook for light vehicle production in North America is 15.8 million vehicles, up slightly from the previous forecast, and 16.4 million vehicles in Western Europe, unchanged from the prior forecast. The outlook for North American Class 8 truck production is 340,000 units in fiscal year 2006, also unchanged from the previous forecast. In Western Europe, the company is raising its outlook for heavy- and medium-duty trucks to 439,000, an increase of 14,000 units.

“The company’s sales for fiscal year 2006 will remain strong, specifically within the North America Class 8 truck market, and we are forecasting full-year sales to be approximately $9 billion,” McClure said.

The company is raising its full-year guidance and expects income from continuing operations, before special items, to be in the range of $1.65 to $1.75 per diluted share, up from the previously forecasted range of $1.60 to $1.70 per diluted share.

“Based on our continued focus on working capital improvements and our strong results year-to-date, we are also increasing our free cash flow forecast to the range of $200 million to $225 million, up from the previously forecasted range of $120 million to $170 million,” said Jim Donlon, senior vice president and CFO.

McClure added, “We are starting to see the financial and operational benefits of restructuring the company, specifically within the LVS business group, and we have made significant progress toward our goal to divest our LVA businesses. We are committed to improving our performance, executing our

strategy and capitalizing on the significant opportunities we see across our businesses and in the global markets.”

Forward-Looking Statements

All earnings per share amounts are on a diluted basis. The company’s fiscal year ends on the Sunday nearest Sept. 30, and its fiscal quarters end on the Sundays nearest Dec. 31, March 31 and June 30. All year and quarter references relate to the company’s fiscal year and fiscal quarters, unless otherwise stated.

This press release contains statements relating to future results of the company (including certain projections and business trends) that are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements are typically identified by words or phrases such as “believe,” “expect,” “anticipate,” “estimate,” “should,” “are likely to be,” “will” and similar expressions. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to global economic and market cycles and conditions; the demand for commercial, specialty and light vehicles for which the company supplies products; risks inherent in operating abroad (including foreign currency exchange rates and potential disruption of production and supply due to terrorist attacks or acts of aggression); availability and cost of raw materials, including steel; OEM program delays; demand for and market acceptance of new and existing products; successful development of new products; reliance on major OEM customers; labor relations of the company, its suppliers and customers, including potential disruptions in supply of parts to our facilities or demand for our products due to work stoppages; the financial condition of the company’s suppliers and customers, including potential bankruptcies; possible adverse effects of any future suspension of normal trade credit terms by our suppliers; potential difficulties competing with companies that have avoided their existing contracts in bankruptcy and reorganization proceedings; successful integration of acquired or merged businesses; the ability to achieve the expected annual savings and synergies from past and future business combinations and the ability to achieve the expected benefits of restructuring actions; success and timing of potential divestitures; potential impairment of long-lived assets, including goodwill; competitive product and pricing pressures; the amount of the company’s debt; the ability of the company to continue to comply with covenants in its financing agreements; the ability of the company to access capital markets; credit ratings of the company’s debt; the outcome of existing and any future legal proceedings, including any litigation with respect to environmental or asbestos-related matters; rising costs of pension and other post-retirement benefits and possible changes in pension and other accounting rules; as well as other risks and uncertainties, including but not limited to those detailed from time to time in filings of the company with the SEC. These forward-looking statements are made only as of the date hereof, and the company undertakes no obligation to update or revise the forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by law.

Non-GAAP Measures

In addition to the results reported in accordance with accounting principles

generally accepted in the United States (“GAAP”) included throughout this press release, the company has provided information regarding income from continuing operations, operating income and diluted earnings per share before special items, which are non-GAAP financial measures. These non-GAAP measures are defined as reported income or loss from continuing operations, operating income and reported diluted earnings or loss per share plus or minus special items. Other non-GAAP financial measures include “net debt” and “free cash flow.” Net debt is defined as total debt less the fair value adjustment of notes due to interest rate swaps and cash. Free cash flow represents net cash provided by operating activities less capital expenditures.

Management believes that the non-GAAP financial measures used in this press release are useful to both management and investors in their analysis of the company’s financial position and results of operations. In particular, management believes that net debt is an important indicator of the company’s overall leverage, and free cash flow is useful in analyzing the company’s ability to service and repay its debt. Further, management uses these non-GAAP measures for planning and forecasting in future periods.

These non-GAAP measures should not be considered a substitute for the reported results prepared in accordance with GAAP. Neither net debt nor free cash flow should be considered substitutes for debt, cash provided by operating activities, or other balance sheet or cash flow statement data prepared in accordance with GAAP, or as a measure of financial position or liquidity. In addition, the calculation of free cash flow does not reflect cash used to

service debt or cash received from the divestitures of businesses or sales of other assets and thus does not reflect funds available for investment or other discretionary uses. These non-GAAP financial measures, as determined and presented by the company, may not be comparable to related or similarly titled measures reported by other companies.

Set forth on the following pages are reconciliations of these non-GAAP financial measures, if applicable, to the most directly comparable financial measures calculated and presented in accordance with GAAP.
